Description

Designed for Processing in Laser Powder Bed Fusion (PBF-LB) Systems 


MetcoAdd™ 625 is a family of nickel-based superalloy powders with chemistry similar to AMS 5666 bar material. 


Room temperature static properties of PBF-LB processed and heat treated material coupons have been shown to be comparable to those of AMS 5666. 


For reference purposes Oerlikon has processed MetcoAdd 625A using fixed parameters and 40 μm layer thickness to provide data below. Additional testing has been performed by an extensive network of consortia and customer partners on a broader range of machine types. Properties may be optimized based on application specific requirements.

This material data has been provided by Oerlikon Metco.

All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
